RETAMAX™ is formulated with potent retinol (1.0%) blended with plant stem cell antioxidants and biomimetic proteins in an exclusively designed micronized emulsion system for rapid delivery of ingredients. It aids in skin rejuvenation by triggering the natural formation of collagen and encouraging the restoration of the skin barrier function by up-regulating the production of hyaluronic acid, the skin's most vital natural hydrating factor.

About Zein Obagi, M.D.Researcher, innovator, scientist, published author, lecturer and board-certified dermatologist, Dr. Zein Obagi has achieved international renown as a leading authority on skin rejuvenation. He is the ZO Skin Health, Inc. founder and medical director and is responsible for the development of new skincare treatments, protocols and products to achieve healthy skin.

Over 20 years ago, Dr. Zein Obagi pioneered the concept of skin health and conceived of, and brought to market, a line of medical skincare products – the original Obagi Nu-Derm® System – that transformed aging skin. Dr. Obagi founded WorldWide Products, which produced and marketed the original Obagi Nu-Derm® System. At that time, Dr. Obagi merely intended to challenge the norms of traditional skin care. Instead he shattered the status quo. Today his ideas about skin health are no longer surprising; they have become mainstream. Subsequently WorldWide was purchased by Obagi Medical Products, Inc., a company with which Dr. Obagi no longer has any affiliation, but which retained his family name (Obagi®) as their trademark.

ZO Skin Health, Inc. and Dr. Obagi have no business relationship with Obagi Medical Products, and Obagi Medical Products does not sell or endorse using any ZO® product.
